Crankcase for heat engine and heat engine

Abstract

The invention discloses a crankcase for a heat engine and a heat engine. The crankcase for a heat engine includes a crankcase body, and cylinder liner holes are provided on the upper mounting surface of the crankcase, and four cylinder liner holes are used as a cylinder liner unit, and a plurality of cylinder liner units are provided; The crankshaft is installed inside, and the crankshaft hole for installing the crankshaft is opened on the crankcase body; in the same cylinder liner unit, the four cylinder liner holes are arranged in pairs on both sides of the central axis surface, and the four cylinders The sleeve hole is used as a vertex on the mounting surface to form a quadrilateral; all the cylinder liner holes and the central axis form a V-shaped structure, and the axes of all cylinder liner holes point to the rotation axis of the crankshaft hole; in the same cylinder liner unit, the cylinder liner holes The included angles between the shaft and the crankcase mid-shaft surface are different in pairs. The crankcase for the heat engine provided by the invention adopts a novel V-shaped structure design to realize the transmission of the multi-cylinder heat engine, which can improve the working stability and reliability of the heat engine.

Description

technical field [0001] The present invention relates to the technical field of power equipment, and more specifically relates to a crankcase for a heat engine and a heat engine equipped with the crankcase for a heat engine. Background technique [0002] Heat engine, also known as Stirling engine, is an external combustion, closed cycle reciprocating piston heat engine. The working principle of the heat engine is as follows: use hydrogen, nitrogen, helium or air as the working medium, and work according to the Stirling cycle. The closed cylinder of the heat engine is filled with a certain volume of working medium. One end of the cylinder is a hot chamber, and the other end It is a cold chamber, the working fluid is compressed in the low-temperature cold chamber, and then flows into the high-temperature hot chamber to be heated rapidly, and the expanded work fuel is continuously burned in the combustion chamber outside the cylinder, and is transmitted to the working medium thr...

AI Technical Summary

Problems solved by technology

[0008] Although the existing crankcase meets the design requirements of the heat engine, its overall structure is asymmetrical, which increases the vibration and noise of the heat engine.

Moreover, the local design of the crankcase is relatively complicated, especially the unique cover part of the free end, which greatly increases the difficulty of casting

In addition, the output shaft is installed in the crankcase by means of plug-in, which increases the difficulty of the installation of the output shaft
